64775778 ÷ 75 
We want to figure out the number of times 64775778 can be divided by 75.

Advancing to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 75

Moving on to step 2:
If we divide 64 by 75, we get 0 and a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 75

Going ahead to step 3:
The number 75 fits into 647 8 times, leaving a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 600 from 647 to get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 75

Step 4:
477 divided by 75 is 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 86.0
The remainder is 27 after subtracting 450 from 477.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 75

Let's proceed to step 5:
When dividing 275 by 75, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 863.0
Subtracting 225 from 275 leaves us with 50.
Grab the next digit (7) from the dividend, add it to 50, then carry on: 507 / 75

On to step 6:
75 can be fit into 507 6 times, resulting in a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 8636.0
Subtract 450 from 507 to get 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 75

Moving on to step 7:
75 can be fit into 577 7 times, resulting in a remainder of 52.
The next digit of our result is 7. 
Result so far: 86367.0
Deduct 525 from 577 and we're left with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 75

Let's proceed to step 8:
75 can be fit into 528 7 times, resulting in a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 863677.0
If we take 525 away from 528, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
If we divide 30 by 75, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 863677.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
75 can be fit into 300 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 863677.04
The remainder is 0 after subtracting 300 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
75 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 863677.04
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
75 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 863677.04
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 863677.04, and the remainder is 0.0.
